1 Claim.

This invention relates to windows and particularly to windows having two sashes commonly known as the double hung type.

The primary object of the invention is to 5 provide new and novel means for swingingly mounting double hung sliding sashes to the frame.

A further object is to provide an improved hinge construction whereby the upper and lower sashes may be both hingedly connected to the frame.

Another object is to provide novel means for detachably connecting certain window stops so that the: sashes of double hung windows may be swung inwardly.

5 A further object is to provide new and novel means for maintaining the weight cord in proper position when the sashes are being swung.

A still further object is to provide a novel hinge construction for double hung windows to prevent slidable movement of the sashes when they are swingingly connected and to prevent swinging movement of the sashes when they are arranged in normal sliding position.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

The invention comprises in general a window having upper and lower sashes which are normally slidably mounted. Means are provided for ing movement of the windows. Hinges are fastened to each sash and have parts thereof which engage sockets provided in a part of the frame or stops. A socket is provided in one face of the frame to receive a member having a bar provided at its lower end. This member is connected to the face cord to keep the face cord in position when the windows are to be swung.

Referring to the drawings, 1 designates generally a window frame in which upper and lower sashes 2 and 3 respectively are slidably mounted 7 in the usual conventional manner. .The upper T i and lower sashes are counter-balanced by means of weights 4. connected to cords 5 which pass over pulleys 6 in a manner well knownin the art. 7 A semi-detachable lower hinge member 7, Fig. 3, is fastened to the front face of each sash and cooperates with a socket member 8 fastened to the side of an inner stop 9.

The hinge member '7 comprises a plate member 10 which is adapted to lie substantially flush with the face of the sash. This hinge member is dished inwardly as indicated at 11, and a hinge leaf member 12 having integral upper and lower pins 13 is pivotally mounted in a part of the 35 A bead-shaped member or knob 14.15 integrally connected to the body 12 and is adapted to cooperate with the socket member 8.

The socket member 8 comprises a body 15 which is recessed in the side of the frame or the i inner stop 9.. This socket member has a relatively large notch 16 provided in its face 17 and communicates with a substantially elongated slot i8.- The notch 16 and. slot 18 permit communication with the recess or compartment 19 provided in the body. or socket member 8, Fig. 3. An upper hinge member 20 is properly spaced above the hinge member 7 and is also recessed in the front face of each upper and lower sash. This hinge member also comprises a dished portion 21 into which a semi-detachable hinge leaf 22 engages. This hinge or leaf has a body portion 23 to which upper and lower pins 24 are fastened. These pins pivotally engage a part of the member 20. A bead or knob 25 is integrally formed on the front face of the leaf 22 and is adapted to cooperate with an upper socket member 26.

The upper socket member 26 comprises a notch or recess 2'7 which merges into a longer but narrower elongated slot 28. The notch 27 and the slot 28 communicate with a recess or compartment 29 provided in the socket member 26. A closure 30 is pivotally connected to the body of the socket member 26 as indicated at 31, Fig. 4. This closure lies flush with the front face of the member 26, and it is provided to prevent vertical slidable movem nt of the sash when the hinges are operatively connected with their cooperating sockets. When the hinge members are operatively engaged with their socket members, each sash may be swung provided suitable means are employed for removing certain of the stops and for holding the window cords after they are disconnected from the sash.

A member 32 cooperates with a socket member 33 for holding the cord when it is disconnected from the sash and thereby prevents the weights from pulling the cords around the pulleys 5 and into the weight boxes. The member 32 is dished at 34 between its upper end 35 and its center or medial portion 36. Holes 37 and 38 are provided in the end 35 and the portion 36 through which the cord 5 is passed. An outwardly extending pin 39 is rigidly connected to the dished shape portion 34 and is adapted to bite into the cord to prevent it from being pulled through the holes 37 and 38. A knob or ball 40 is provided on the lower end of the member 32 and is adapted to engage a recess 41, Fig. 9, provided in the socket 33. This socket member is recessed into the bottom of the frame as clearly shown in Fig. 6. A slot 42 is cut in the body of the socket member 33 to accommodate the part 43 of the member 32, Figs. 8 and 9. A similar arrangement is applied to the outer side face of each sash for making the proper connection to the sash.

In order to permit inward swinging of the lower sash 3, a part of the inner stop 44 must be removed. The stop 44 is detachably connected to the frame 45, Fig. 9, by means of a revolubly mounted member 46 engaging a cooperating member 47. A tubular member 48 is recessed into the stop 44 and is provided with an annular shoulder 49 which engages the outer face of the stop. The revolubly mounted member 46 has a cylindrical portion 50 provided thereon to which a stem 51 is integrally attached. The stem 51 is provided with threads or a spiral 52 which engages a female threaded portion 53 formed in the member 47. A spring 54 is arranged between the end 55 of the part 50 and the bottom 56 of the tubular member 48. This spring normally urges the member 46 outwardlyto the right, Fig. 10, but the member 46 with its cooperating stem 52 cannot be withdrawn from the tubular member or shell 48 inasmuch as the threads or spiral 43 will not pass through the opening 57 provided in the shell. The handle 58 of the member 46 is unscrewed to disengage the threaded end 52 from its cooperating threaded socket 53. After disengagement the stop 44 may be removed and the lower sash swung inwardly.

The upper sash 2 operates in exactly the same manner as the lower sash, being provided with the upper and lower hinge members 20 and '7 respectively. These latter hinge members cooperate with upper and lower socket members 26 and 8 respectively. These socket members may be arranged in the middle or dividing stop 59, Fig. 6. The opposite middle or dividing stop 60 must necessarily be removed to permit the upper sash to be swung inwardly. The dividing strip 60 is held at its upper end by the upper sash 2 when it is in raised position and is prevented from moving laterally due to being recessed into the side of the frame and also due to the upper and lower sash. To prevent side movement of the dividing strip 60, a holding member 61 is provided. This member 61 comprises a body portion 62 which is adapted to rest on top of the stool 63 of the window. Prongs 64 are provided on the bottom surface of the member 61 and are driven into the stool. An upwardly extending flange or lip 65 is integrally connected thereto and engages with the side face 66 of the strip 60 to prevent sidewise movement thereof. This strip 66 is divided from its upper portion, side play being permitted between the two portions thereof. To remove the strip, it is first pushed upwardly a slight distance until the bottom 67 thereof passes over the top 68 of the flange or lip 65. The strip can then be pulled to the left, Fig. 5, to free it from the member 61 and then removed from position.

After the hinges are engaged with their cooperating sockets, and the strips 44 and 60 are removed, the sash cords 5 are fastened in place by means of the ball 40 engaging the socket member 33. The windows are then free to be swung inwardly as shown in Fig. 2.

Operation In operation the lower sash is lifted a slight distance until the bead or knob 14 on the hinge member '7 is directly opposite the slot or recess 16 and its cooperating socket member. The hinge leaf 12 is then swung until the knob or bead 14 engages the slot 16. The sash is then lowered until the hinge member 20 is opposite its cooperating socket member 26. The hinge leaf 22 is then moved so that the bead or knob 25 engages the socket or slot 27 in the socket member 26. Before the engagement of the member 25 with the slot, the closure 30 is raised to the position shown in dotted lines in Fig. 4. The sash is then lowered so that the head or knob 14 will engage the slot 18 in the socket member 8. The bead or knob 25 will then engage the slot 28 in the socket member 26. The closure 30 then swings downwardly as shown in full lines in Fig. 4. The hinge members '7 and 20 are thus hingedly connected with their cooperating sockets 8 and 26 respectively and vertical movement of the sash cannot be had due to the closure 30 locking the knob or bead 25 in position in its cooperating socket member. After the hinge members are engaged with their cooperating sockets in the manner just mentioned, the strip 44 is removed by turning the member 46 in a counter-clockwise direction. The lower sash is then free to be swung inwardly. When the free edge of the sash clears the window frame, the sash cord is disconnected from the sash and held in place by means of the sash cord member 32 having interlocking engagement with the socket member 33. This engagement prevents the sash weights from pulling the cord around the pulleys and into the weight boxes. The upper sash 2 is then slid downwardly, the hinge members '7 and 25 on the upper sash being engaged with their cooperating sockets in the same manner as just described relative to the lower sash. When the hinge members on the upper sash are engaged by their cooperating sockets, the dividing strip 60 is removed to permit inward swinging movement of the upper sash. When this upper sash'has cleared the window frame, the sash cord on the free side is supported in the same manner as described relative to the sash cord in the lower sash. Both the upper sash and the lower sash are then free to be swung inwardly as shown in Fig. 7.

To bring each sash back to its original position, the upper sash 2 has the sash cord connected thereto and then swung back to position. The dividing strip 60 is inserted in place and the hinge members are disconnected from their cooperating socket members. The sash 2 is then free to be slid upwardly to its normal original position.

The lower sash is then swung on its pivots to closed position and the inner stop 40 is replaced, this stop being held in position by means of the member 46.

The hinge members '7 and 20 are then disconnected from their cooperating sockets and the lower sash is free to slide as usual.

The invention provides new and improved means for swingingly mounting double hung sashes. The hinges and their cooperating sockets permit the double hung sash to be swingingly connected to the window frame, and when these hinges are connected with the sockets, vertical slidable movement thereof is prevented. The member 46 permits easy removal of the inner stop and the member 61 allows the dividing stop to be easily removed and replaced. The members 32 and 33 hold the sash cords securely in place when the double hung sashes are swingingly mounted.

It is to be understood that the positioning of the hinge members and various other parts may be changed at will and that the two sashes may be swung when both are in up position or the upper sash may be swingingly mounted before the lower sash.

Changes may be made in the form, construction, and arrangement of the various parts without departing from the spirit of the invention or sacrificing any of its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claim.

A hinge construction for pivotally mounting a double hung slidable sash in its frame, comprising a plate member adapted to be seated in a recess in the sash and adapted to lie flush with the outer face thereof, said plate member having a recess, a hinge leaf pivoted to said plate memher and disposed in the recess of the said plate member, said leaf having a knob formed thereon, a second plate member adapted to be seated in a recess in the frame, said second plate member having a recess and a slot provided therein, said slot communicating with the last named recess, said knob being engageable with the second plate member and receivable in said last named recess and slot, and a swinging closure mounted on a horizontal pivot and connected to the second plate member and adapted to close the recess in the second plate member whereby the knob will be retained in the said slot, when said knob is interengaged with the second plate member, said closure lying flush with the face of the second plate member.
